IAHS is pleased to announce the recipients of the International Hydrology Prize (Dooge medal and Volker medal) for 2026. 

The International Hydrology Prize is awarded annually by IAHS, with UNESCO and WMO, to two people who have made an outstanding contribution to hydrological sciences.

This year's prize selection was especially competitive, with 15 nominations received, making this one of the most distinguished pools of candidates we have ever seen. The 2026 recipients emerged at the top of this highly accomplished group of excellency. Their contributions to hydrology have not only advanced scientific understanding but have also had a significant global impact.

Nominations for the annual Prize are made by National Committees to IAHS, National Committees to the UNESCO-IHP or National Hydrological Advisors to the WMO, and forwarded to the Secretary General of IAHS for consideration by the Nomination Committee. The Committee consists of the President and a Vice-President of IAHS and representatives of UNESCO and WMO.

The award ceremony is scheduled to take place during the IUGG General Assembly 2027 in Incheon, South Korea (16-22 July). 

We extend our warmest congratulations to the winners and express our deep appreciation to all nominees and nominators. Several of the candidates would undoubtedly have been awarded the prize in any other year, and we encourage renewed nominations in the future. This year’s process clearly demonstrates the value and prestige associated with the International Hydrology Prize and reaffirms its role in recognising the world’s leading hydrological scientists.
